Abstract: Light-emitting diode (LED) packages and, more particularly, LED packages with transformation and shifting of pulse width modulation (PWM) signals and related methods are disclosed. Discrete LED packages are arranged for cascade communication. Each LED package includes one or more LED chips, and each LED package is separately capable of receiving communication from a data stream, controlling operation of the one or more LED chips, and performing transformation and shifting of received PWM signals.
